JJRC H31 - Waterproof Drone
Waterproof drones usually move in a much higher price range, which already comes from a separate design. The fact that the JJRC H31 should actually be protected from submersion is therefore more than unlikely at first sight. However, there are already several test reports and videos on the net showing that the JJRC H31 quadrocopter also survives a submersion lasting several minutes and remains fully airworthy. The board located in the drone case is doing with a thick layer of glue overdrawn. However, the engines are exposed, which also have no special water protection.

In various test reports, the short transmission range was also criticized and that the drone in case of a water landing does not float on the water, but goes down and thereby engines and the battery are endangered.
